# Current Design Flaws

This section documents some bad/buggy designs in PixivFE's design, both frontend and backend.

## "Switchers"

Switchers should know what the current value is.

## Low Quality Go Module: net/url

`url.Path` is stored decoded (no %XX). `url.Scheme` is stored without `://` (mandated by RFC). Not sure why Go does that. Felt like this is bound to cause some nasty bug on decoding and encoding.

Current proxied URLs don't have weird characters in them. Hopefully it stays this way.

Solution: Replace "net/url" with a better third-party module
